GAGE.

SPECIFICATION forming part of Letters Patent No. 760,297, dated May 1'7, 1904.

Application filed June 12, 1903- Serial N0. 161,124. (NO model.)

To all whom, it 'ntll/y concern.-

Be it known that I, ANTONIO BASOLA, a citizen of the United States, and a resident of New York, in the county and State of New York, have invented certain new and useful Improvements in Gages, of which the following is a specification.

My invention relates to an improvement in gages of that kind which are used for transferring distances from one object to'anothcr. My device may also be used in comparing or transferring angles from one object to another and also for measuring the depth of recesses or holes, whether the same be for the purpose of comparison or not.

In the drawings, Figure 1 is a sideelevation of my device. Fig. 2 is a view of the arm and pointer, taken at right angles to the I position of the parts as shown in Fig. 1. Fig.

3 is an edge view of the standard. 1 with the base-piece and arm in place.

Corresponding parts in all the figures are denoted by the same reference characters.

In copying objects of sculpture or in many other analogous uses it is often necessary to compare the object being operated upon with a model to see whether any particular surface or point has been brought to the exact level desired. For instance, in executinga carving, whether in stone or wood, it is necessary to be able to determine whether a recess or hole which is being worked out is of the same depth as in the model. For this purpose devices of various kinds have been used. My device is intended to facilitate such operations as these and also to facilitate comparison of angles of surfaces.

My device is made of simple and cheaplymade forms, and these are so constructed that they are durable and conveniently manipulated.

There are four principal parts to my device: first, the base-piece, which, as herein shown, consists of a flat plate 3, having a longitudinal slot 4. therein; second, the standard 1, which, as herein shown, consists of a flat bar or plate bent upon itself so as to consist of two parallel arms alike in construction and separated from each other a sufficient distance to permit the base-piece 3 and the arm 6 to lie and be clamped between them. The standard 1 is provided with a longitudinal slot 2, extending throughout the greater portion of its length. The arm 6, which is placed between the two halves of the standard above the basepiece 3, consists of a flat bar provided with a longitudinal slot 7. The base-picce 3 and arm 6 are both secured. in place between the two sides of the standard by a clamp or set screw 5, securing the base-piece, and a similar screw 8, securing the arm in place. The arm 6 carries a pivotal or rotatable guide-piecc for the pointer 11. This guide-piece, as herein shown, consists of a piece of flat metal or plate having its ends turned up to form lugs or cars 9, which are provided with holes adapted to snugly receive the pointer 11, said pointer consisting of a small round rod. The pivotpiece 8 is secured in place upon the arm by means of a clamp-screw and nut 10, which passes through the slot in the arm. The pointer 11 is provided above the pivot-piece 8 with a stop 12, adapted to slide thereon and to be secured in place by the clampingscrew 13.

By the construction above described it will be seen that the various parts of the device may be adjusted upon each other by shifting upon the clamping-pins and also by turning thereon, so as to be made to assume almost any position. The pointer 11, it will be noticed, may be moved in its guide after having been adjusted upon the model, so that it may be drawn out of a hole or recess and then be brought back to exactly the same adjustment, so that its use will in many cases be greatly facilitated.

My device will be found very convenient both for measuring the level of surfaces and also for comparing angles, in which case the arm 6 would be used to determine the angle. Ordinarily the base-piece 3 would be placed upon some surface of the model or adjacent the model, the lower end of the standard being at the same time brought against some vertical surface. After adjusting the arm and pointer 11 so that the point thereof touches the model at the desired point the same may be transferred to the work and applied to the same point thereof. If the pointer is raised in its guide and the surface has not been reduced to the proper level the amount of such reduction remaining to be done will be indicated by the space between the stop 12 and the end of the pivot member 8. To furnish a slight clamping or resisting action upon the pointer 1 1 in its movement through its guides, a friction-spring may be employed, the same, as herein shown, consisting of a flat strap 14, secured by one end to the base of the pivot member 8 and by its other end engaging the surface of the pointer 11.

I do not desire to be understood as limiting myself to the details of construction and arrangement as herein described and illustrated, as it is manifest that variations and modifications may be made in the features of construction and arrangement in the adaptation of the device to various conditions of use without departing from the spirit and scope of my invention and improvements. I therefore reserve the right to all such variation and modification as proper fall within the scope of my invention and the terms of the following claims. 7

Having thus described my invention, I claim and desire to secure by Letters Patent 1. A gage, comprising a standard composed of a bar bent upon itself to form two parallel bars, said bars having registering longitudinal slots, an arm interposed between said bars, and having a longitudinal slot, a clamping-screw passing through the slots in said bars and arm, a block and clamp-screw therefor adjustable in the slot of the arm, a pointer slidable in guides upon said block, a second arm interposed between said bars and having a longitudinal slot, and a clampingscrew passing through the slots in said bars and said second arm, substantially as described.

2. A gage, comprising a standard composed of a bar bent'upon itself to form two parallel bars, said bars having registering longitudinal slots, an arm lying between the two bars of the standard and having a longitudinal slot, a clamping-screw passing through the slots of standard and arm, a block and clamp-screw therefor adjustable in the slot of the arm, a pointer slidable in guides upon said block, and an adjustable stop upon the pointer adapted to limit in one direction the movement of the pointer within its guides.

In testimony whereof I have signed my name in the presence of the subscribing witnesses.

ANTONIO BAS'OLA.
